Re: Free Meshers - Tetgen and Netgen

Hi Selopez.
A big thanks from me for that excellant procedure - very informative. It has made a massive difference in getting a speedy first time successful Tetgen mesh.
I'm very happy now.. :lol:

Regards..
Tim.

Re: How to modify high aspect ratio's of imported stl

Confession time. I have spent too much time on .stl file translations and the problems with the traingles and meshing. If you have not been using the .stp input, i would recommend experimentating with it. The .stp file translation automatically overides CAD face / part facet setting and converts al...

Re: Ergebnisse sind offensichtlich total falsch. Fehler?

Yes - i too had a problem with 'Force - Distributed Uniformly'.

Only when the English Documents arrived did i discover ' Help / Spider / Constraints /PDF' etc etc.

Now all is understood.

Free Meshers - Tetgen and Netgen

I am wondering about the development of these programs and the implimentation within Z88 Aurora. In another post Martin said the development of these was completely outside of Z88 team. I have been wandering around google and found this Netgen example: OpenCascade IGES and STEP support The integrati...

Re: How to modify high aspect ratio's of imported stl

Yes - very neat. Selopez, i need your recipe! Incase there's any other interested parties out there, I have been experimenting with splitting surfaces by 'imprinting lines' 1. This gives a control of triangle ratios in the stl conversion process which my CAD software didn't provide. 2. Provides / ma...

Re: How to modify high aspect ratio's of imported stl

Here is another example using Netgen at the finest mesh size possible. In this case size 1.5 - this is NOT the correct procedure as its a waste of computational time and produces massive data which is slow to work with. The only advantage is finer facets but these are still not fine enough and are i...

How to modify high aspect ratio's of imported stl

Does anyone know a free solution to altering high aspect ratio of facets typically produced in cylindrical 3D models. As i show, in Tetgen meshing the solution is very complex / irregular and can cause computation problems. However, it doesn't alter the facet length, so the curve has the original st...

Re: Comments on AURORA V2

Just to also praise the V2 documentation. I struggled alot with V1. But when the V2 came out, even without the english help files to guide me i made much better progress. Now i have downloaded the 'English' version with english help files etc. Gone through the Help files / Video's /Spider / Spider P...

Re: Picking surfaces

Dear Z88 team. Well, i have to thank you very much - The difference between V1 and V2 is HUGE. A number of months ago V2 was announced and a deadline date was set and you have met this. So smiles all round as i see in Facebook. I have for many years paid a great deal of money in subscription service...

Hi Markus. Thank you Markus. You have prompted me to investigate further - i am a bit behind the times - if you understand me. I can select the pdf text and then choose the 'Adobe Export PDF' service if i had the account. ( ps -it isn't too expensive ). However, i can't 'cut' the text and 'paste' in...

Thanks, V2 up and running without hitch in english. Just scratching my head a little at the V1 / V2 differences- i knew FEA wasn't going to be easy!

Dear Prof. Reig. Of course, when it comes to resources, there's never enough! Glad to hear you'll be keeping the deadline pressure on your team although i'm sure their sighing in private. I suppose i will just have to be patient.. or, battle it out. Hmmn, i'll try the latter :lol: I'd like to pre-or...
